Certified Vertical Closed Loop Driller

Advances in geothermal technologies and their usage created the need for a specific voluntary certification designation for geothermal drillers. NGWA responded to this need with the designation of Certified Vertical Closed Loop Driller (CVCLD).

The CVCLD is considered an independent designation from the CWD or CWD/PI. The designation reflects an individual who has passed a written exam administered by NGWA that evaluates an individual’s knowledge of the skills and competencies associated with constructing a loop well.

Becoming certified

Once the VCL exam has been passed with a score of 70 percent or better, the applicant can send in application materials consisting of the three below forms:

Certification Agreement Form — applicant agrees to adhere to the statutes of the NGWA Voluntary Certification Program and its policies.

Candidate Reference Form — applicant must provide the names of two references who can verify experience.

Current Affidavit — a signed document claiming the individual has never been convicted of any civil or criminal legal action as a result of professional activities relating to geothermal applications.

Maintaining certification

All certification renewal materials must be received at NGWA on or before December 31 of the renewing year. Renewal materials consist of:

Annual renewal fees

Annual continuing education points — an individual must obtain seven (7) continuing education points each calendar year; four (4) of the seven (7)points required for renewal must be from geothermal/heat pump-related educational offerings, while the remaining three (3) points may be earned within the same continuing education offering pool as a CWD, CPI, or CWD/PI

Current Affidavit — a signed document claiming the individual has never been convicted of any civil or criminal legal action as a result of professional activities relating to geothermal applications.
